Background: Home environment is a core domain in the care of community-dwelling older adults with dementia, but there is no suitable instrument to measure it in China. Objective: To develop and psychometrically test the home environment assessment checklist for community-dwelling older adults with dementia. Methods: A three-step process was performed to develop and test this instrument: 1) based on the evidence-based theory, the checklist was summarized as the main points of evidence from living environment settings among older adults with dementia, 2) the draft tool was assigned to an iterative process of evaluation by a panel of examiners consisting of experts from treatment, nursing and caring, people with dementia and their caregivers, 3) inter-rater reliability and internal consistency were calculated with a sample of 348 caregivers of the older adults with dementia. Results: The HEAC consisted of 71 items in domains addressing safety, stability and familiarity, visual cues, and sensory stimulation. Psychometric evaluation showed that this tool demonstrated sound reliability and validity. Content validity was 0.969 which was established by a panel of experts (n = 10). Inter-rater reliability of two researchers was 0.978, and 0.848 for researchers and caregivers. Test-retest reliability was excellent (ICC = 0.757–0.877) in community-dwelling older adults with dementia 2 week apart. Conclusion: The HEAC is a new tool to help collect the reliable information on the barriers and facilitators of home environment for community-dwelling older adults with dementia and to precipitate the home modification process to improve the quality of care for people with dementia and their caregivers in daily life.

Recent research has suggested that the breadth and evenness of activity and activity diversity contribute to health outcomes among older adults. However, few established assessment tools for activity diversity have been developed. This study developed an Activity Diversity Questionnaire (ADQ) for older adults through expert consultation and a preliminary survey among 18 community-dwelling older adults. The diversity score was calculated according to Shannon’s entropy. In study 1, the intraclass correlation coefficients (ICC) of the diversity scores were determined for community-dwelling older adults (n = 30). In study 2, concurrent validity was tested with participants receiving comprehensive health checkups at the Itabashi ward in Japan in 2018 (n = 766). The correlation coefficients of the diversity scores were then calculated in reference to the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence. The final version of the ADQ consisted of 20 total items with excellent test-retest reliability (ICC = 0.84) and moderate correlations with both the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence (r = 0.48 and 0.60, respectively). The ADQ was developed through scientific procedures and revealed sufficient reliability and validity. As such, it is a scientifically validated tool for assessing activity diversity among older adults.

Although popular in clinical settings, little is known about the utility of all-extremity semirecumbent exercise machines for research. Twenty-one community-dwelling older adults performed two exercise trials (three 4-min stages at increasing workloads) to evaluate the reliability and validity of exercise responses to submaximal all-extremity semirecumbent exercise (BioStep). Exercise responses were measured directly (Cosmed K4b2) and indirectly through software on the BioStep. Test–retest reliability (ICC2,1) was moderate to high across all three stages for directly measured METs (.92, .87, and .88) and HR (.91, .83, and .86). Concurrent criterion validity between the K4b2and BioStep MET values was moderate to very good across the three stages on both Day 1 (r= .86, .71, and .83) and Day 2 (r= .73, .87, and .72). All-extremity semirecumbent submaximal exercise elicited reliable and valid responses in our sample of older adults and thus can be considered a viable exercise mode.

Abstract Often the goal of physical therapy is to reduce morbidity and prevent or delay loss of independence. The purpose of this article is to describe issues to consider when selecting measures of physical function for use with community-dwelling adults over the age of 65 years. We chose 16 measures of physical function for review because they have been used in studies of community-dwelling older adults and some psychometric properties of reliability and validity have been described in the literature. Three major issues are discussed: (1) appropriateness of the measure for community-dwelling older adults, (2) practical aspects of test administration, and (3) psychometric properties. These issues are illustrated using examples from the 16 measures. Two scenarios, applying the measures to the assessment of physical performance of community-dwelling well older people and to the assessment of physical performance of community-dwelling frail older people, are used to illustrate how this information can be used.
